Abstract

A joint data repository on flowage lakes of the world and long-term flow variations in the rivers they regulate has been formed. The specific features of the flowage lake parameters have been analyzed along with their dependence on the characteristics of the lakes. A hypothesis has been proposed implying the global invariance of the coefficient of water exchange of lakes with respect to the average volume of flow through the lakes. The effect of the coefficient of lake water exchange on the long-term flow variations of the rivers regulated by the lakes has been studied. It has been shown that an increase in this coefficient is accompanied by a decrease, on the average, of the correlation between the annual, maximal, and minimal flow of successive years, as well as the average orders of the autoregression models describing the long-term variations of all types of flow. The effect of intermittent nonstationarity has been described for the series of annual runoff values for some lake-containing rivers.

世界流动湖泊：数量特征及其对含湖河流流量变化特征的影响分析

摘要

已建立了一个关于世界流量湖泊及其监管河流的长期流量变化的联合数据存储库。已经分析了流动湖泊参数的特定特征，以及它们对湖泊特征的依赖性。已经提出了一种假设，该假设暗示着湖泊的水交换系数相对于流经湖泊的平均流量的全局不变性。研究了湖泊水交换系数对湖泊调节河流长期流量变化的影响。已经表明，该系数的增加平均伴随着连续年年流量，最大流量和最小流量之间的相关性降低，以及描述所有类型流量的长期变化的自回归模型的平均阶数。对于某些含湖河流的一系列年径流值，已经描述了间歇性非平稳性的影响。
